use of io.temporal.samples.metrics.activities.MetricsActivitiesImpl in project samples-java by temporalio.

the class MetricsWorker method main.

public static void main(String[] args) {
    // Set up prometheus registry and stats reported
    PrometheusMeterRegistry registry = new PrometheusMeterRegistry(PrometheusConfig.DEFAULT);
    // Set up a new scope, report every 1 second
    Scope scope = new RootScopeBuilder().tags(ImmutableMap.of("workerCustomTag1", "workerCustomTag1Value", "workerCustomTag2", "workerCustomTag2Value")).reporter(new MicrometerClientStatsReporter(registry)).reportEvery(com.uber.m3.util.Duration.ofSeconds(1));
    // Start the prometheus scrape endpoint
    HttpServer scrapeEndpoint = MetricsUtils.startPrometheusScrapeEndpoint(registry, 8080);
    // Stopping the worker will stop the http server that exposes the
    // scrape endpoint.
    Runtime.getRuntime().addShutdownHook(new Thread(() -> scrapeEndpoint.stop(1)));
    // Add metrics scope to workflow service stub options
    WorkflowServiceStubsOptions stubOptions = WorkflowServiceStubsOptions.newBuilder().setMetricsScope(scope).build();
